• Port-based ACLs are applied on ports directly connected to an FCF and on server-facing ENode ports.
• Port-based ACLs take precedence over global ACLs.
• FCoE-generated ACLs take precedence over user-configured ACLs. A user-configured ACL entry 
cannot deny FCoE and FIP snooping frames.
Figure 10-2 shows an MXL 10/40GbE Switch used as a FIP snooping bridge in a converged Ethernet 
network. The ToR switch operates as an FCF for FCoE traffic. Converged LAN and SAN traffic is 
transmitted between the ToR switch and an MXL switch. The MXL switch operates as a lossless FIP 
snooping bridge to transparently forward FCoE frames between the ENode servers and the FCF switch.
